Lamp Module Replacement Procedure
A replacement lamp module may be purchased (P/N 69736) from your selling
dealer an authorized AmPro Service Center or AmPro Corporation.
Replacement
Procedures
The lamp module is accessed on the rear of the projector. It consists of a 500W Xenon
lamp mounted in a heat sink and housed in a protective plastic assembly.
!
The lamp assembly is very hot during normal operation. To minimize risk of
potential burns to the skin, allow time for the lamp assembly to cool to room
temperature before servicing. Be sure to handle the lamp by its plastic housing only.
!
The lamp is under great pressure at all times and may explode. To reduce the risk
of personnel injury and/or property damage, when servicing the projector (display
engine) wear safety glasses and allow the lamp to cool completely.

STEP 1. De-energize the projector and remove the ac power cord.

STEP 2. At the rear of the projector, unlock the lamp module access door and lift the
hinged access door up.

STEP 3. Open the two captive latches securing the lamp sub-assembly access door
at the rear of the projector.

STEP 4. Gently, pull the lamp assembly out by its plastic housing.

If the lamp is too tight to remove, loosen the two lamp adjustment screws.

STEP 5. To install the lamp module, slide the lamp assembly in. If the lamp
adjustment screws were loosed, refer to Adjusting the Lamp Module (below). Close
the inner access door, fasten the two captive latches and close the outer access
door.
